Inventor: HASEBE NORIYUKI
IPC: G06F13/00
Filed: 1989-01-31
Abstract: PURPOSE:To promptly detect the no-response fault of terminal equipment by sampling a necessary time when control data are inputted/outputted between a CPU and the terminal equipment normally, and determining a monitoring time. CONSTITUTION:An input/output control detecting part 11, an input/output necessary time counting part 12, and the monitoring time setting part 13 are provided. At the time of the input/output repeated between the CPU and the terminal equipment in a first mode, the maximum value of the input/output necessary time in a certain range is obtained as a monitoring time maximum value, in a second mode at the time of deciding the normality of the terminal equipment, the necessary time is fetched as sampling data, the monitoring time optimum value is determined with the use of the newest constant value, and it is used for the monitor of the terminal equipment fault. Only when the necessary time exceeds the monitoring time optimum value, the monitoring time maximum value obtained in the first mode is used for the monitoring time instead of the optimum value, and the terminal equipment is finally decided. Thus the terminal equipment can be efficiently decided.

As resin, which cures through curing treatment, thermosetting resin, which sets by thermosetting treatment, ultraviolet-curing resin, which cures through ultraviolet-curing treatment or electron radiation curing resin, which cures through electron radiation curing treatment is exampled. The, curing treatment is done under the condition that a base material is pressed by hydraulic pressure against the peripheral surface of the pipe line in order to form a pipe rigidly lined with the tightly adhered material to the inner peripheral surface of the pipe line. Accordingly, even if the hydraulic pressure is released afterwards, the lining pipe has a force for retaining the shape by its own rigidity.

Title: Optical deflection device
Inventor: YOSHIZAWA ATSUTOMO
IPC: G02B26/12
Filed: 1992-02-06
Abstract: PURPOSE:To reduce the inclination of a reflecting mirror surface by deflecting respective pieces of luminous flux by mutually independent rotary polygon mirrors and independently positioning the rotary polygon mirrors on the same rotary shaft. CONSTITUTION:The parallelism between the internal-diameter part 8-1 and reflecting mirror surface 9-1 of the rotary polygon mirror 4-1 which are in contact with the rotary shaft 3 is finished to a tolerance within the surface inclination precision of the mirror surfaces. The polygon mirror 4-1 is made thick enough to deflect and reflect one piece of luminous flux, so the weight is light. Further, the polygon mirror 4-1 is fixed on the rotary shaft 3 without any fitting play. Shrinkage fitting is used for fixing polygon mirror on the rotary shaft 3 and the polygon mirror is fixed based on the internal-diameter part 8-1. In this case, the position on the rotary shaft 3 in a thrust direction is determined by a fitting jig with high precision, so the luminous flux 1 is never missed. Then the polygon mirrors 4-1 and 4-2 are independently positioned and fixed on the same rotary shaft 3. Consequently, they need not be made strict in machining precision, the surface inclination is reduced, and high precision is obtained.

Title: Background level detection system of star sensor using two-dimensional solid-state image pickup element
Inventor: HAMADA AKIHIKO
IPC: H04N5/335
Filed: 1984-02-07
Abstract: PURPOSE:To extract a background component due to stray light distributed uniformly over the entire surface of a CCD together with the mean dark current component of all picture elements of the CCD by passing the video signal of the two-dimensional solidstate image pickup element through a low-pass filter, and averaging output voltages of all picture elements of the image pickup element. CONSTITUTION:A light component 7 inputted to an optical system 6 is inputted to the CCD1 together with stray light 8 generated in the optical system and the video signal of its output is amplified by a video signal amplifying circuit 2 and inputted to the low-pass filter 10. The cutoff frequency of this filter 10 is set lower than the image pickup frequency of the CCD9 to average outputs of all picture elements including star data of the CCD1. Image elements of a star sensor which provide a start image are generally plural and much less than all picture elements of the CCD. Therefore, the amount of information obtained from the star image is smaller than the amount of the background due to the stray light, etc. Consequently, information obtained through the low-pass filter 10 consists of only the dark current component as to all picture elements of the CCD and background component.

Title: Method for measuring hole diameter distribution of virus removing filter
Inventor: HIDAKA HIDETOSHI
IPC: G01N15/08
Filed: 1994-02-18
Abstract: PURPOSE:To realize high sensitivity measurement, especially high sensitivity integrity test of a used filter, by employing a two-phase separation liquid obtained by mixing water and a specific alcohol as a measuring liquid. CONSTITUTION:A two-phase separation liquid obtained by mixing 1-pentyl alcohol, water and ethyl alcohol or methyl alcohol is employed as the measuring liquid. This method is applied to a virus removing filter. The friter material includes cellulose, polyvinylidene fluoride, etc., 1-pentyl alcohol enhances the sensitivity in measurement significantly. The compositional ratio between 1- pentyl alcohol and water can be selected appropriately within a range for producing a two-phase separation liquid and preferably set in the range of 1:1-1:2 by weight ratio because the separation is difficult when the upper layer liquid is abundant. Ethyl alcohol and the like are required for regulating the interfacial tension in order to set a theoretical hole diameter larger than a predetermined value.

Filed: 1988-02-01
Abstract: PURPOSE:To simplify an RF circuit and a procedure by allowing a station desired to be sent early to send a radio wave with 'connection request data' superimposed thereupon for a short time. CONSTITUTION:When a talking key 121 of a mobile station B is depressed, it is confirmed that the frequency to be received is not used anywhere, then a power supply of an RF transmission circuit 119 is turned on by a control section 117. After the RF transmission circuit is made stable, a connection request data generated by a transmission data generating section 118 is modulated by the RF transmission circuit by a high frequency, the radio wave is transmitted toward a base station A and the power supply of the RF transmission circuit 119 is tuned off to stop the radiation of a radio wave. The base station A receives the connection request data and a radio presence deciding circuit 107 after a prescribed time and it is confirmed as to whether or not the reception frequency is used anywhere. Thus, even when the transmission frequency selection circuit is removed, the operating state of the frequency to be transmitted/received is confirmed easily and the circuit and procedure and simplified.

Title: Structure of suspended sliding door
Inventor: TOJO TAKASHI
IPC: E05D15/06
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To always return a suspension wheel to a center position when it is shifted in a horizontal direction by traveling a pair of suspension wheels for suspending a sliding door on a pair of rails inclined in a cross direction. SOLUTION: A rail surface contacted by a suspension wheel A is inclined downward from the left and right side face lower parts of a rail frame E toward a center part by the inclining angle of 15 to 45 degrees, and the suspension wheel is also inclined to be attached to a suspension wheel holding part B. The suspension wheel holding part B is attached to a sliding door D via a free rotary shaft P and a suspension hand Q, and the rotary shaft P allows the suspension hand Q to be swung in a direction orthogonal to the traveling direction of the sliding door D like the pendulum of a wall clock. When the left and right positions of the suspension wheel A are shifted from the center position of the rail frame E, a force for always returning the same to the original positions is applied and thereby the large meandering of the sliding door D is prevented.  Thus, the runner suspension wheel A and the suspension wheel holding part B are prevented from being contacted with the rail frame E or the like to make noises.
